The position of fermentation industry in the national economy is becoming increasingly important, whether it is glutamic acid, antibiotics, vitamins, citric acid or protease, from alcohol to soy sauce and vinegar, amylase or gluconic acid, it involves various industrial sectors such as medicine, food, chemical industry, environmental governance, petroleum extraction, feed, etc.
For the process of technological fermentation, the steps of inclined cultivation of bacterial strains, seed expansion cultivation, fermentation, and product extraction preparation are very important. The large-scale growth of microbial cells is closely related to the suitable environment
1. Pre treatment of fermentation raw materials
Starch based raw materials have been applied in industrial large-scale production of alcohol fermentation, citric acid fermentation, and glutamic acid fermentation
Hydrocarbons are commonly referred to as carbon sources in petroleum dewaxing fermentation, which refers to the process of cooling a certain fraction of petroleum to obtain oil with a freezing point, adding an appropriate amount of inorganic salts for inoculation and fermentation. However, using methane methanol as a carbon source does not require pre-treatment, and can be fermented by adding it in proportion after inoculation
2. Seed expansion cultivation
The method of expanding cultivation adopts solid culture or liquid culture. The stage of seed expansion cultivation is determined by the fermentation scale. During deep fermentation in the fermentation tank, it has developed from batch fermentation to continuous fermentation
There are many factors that affect fermentation, such as temperature PH、DO、 Ventilation, stirring, tank pressure, etc. must be controlled to grasp the fermentation conditions and dynamics. Beijing Jiade's fully automatic fermentation tank products have accurate culture medium concentration, which can not only automatically replenish materials, control temperature, defoam, adjust acidity and alkalinity, but also achieve real-time recording of curve settings. The JD-CCK new remote monitoring system can be connected to a mobile phone to achieve remote monitoring and control of various parameters of the fermentation tank. There is also a one click alarm function, which greatly saves labor and reduces labor costs.
